Abstract: The invention provides improved methods and systems for a precise and selective cross-talk cancellation and pilot tones deletion in optical amplifiers. The method for cancellation of cross--talk among multiple channels occurring in a traditional optical amplifier comprises: detecting tones at an input and an output of a Smart Optical Amplifier that includes a traditional optical amplifier and a Cross-talk Cancellation Unit; comparing the detected tones at the input and output of the Smart Optical Amplifier; generating destructive tones with such amplitudes and phases so as to cancel cross-talk; and eradicating cross-talk at the output of the Smart Optical Amplifier by applying the destructive tones in the Cross-talk Cancellation Unit. Eight different embodiments that correspond to different combinations of traditional optical amplifier types and the type of technology (analog or digital) used in processing and control of signals are described.

Title: Method of forming a sheet metal cup without a mandrel
Inventor: ROES JOHN P
IPC: B21D22/14
Filed: 2002-02-12
Granted: 2007-07-03
Abstract: The invention comprises a method of forming a sheet metal cup without using a mandrel. A cup shaped blank (10) is first produced having a relief (11) on a rim (12) or outer circumference. The blank (10) is clamped in the spinning machine. The relief (11) controls and facilitates the bending process, creating a uniform curve at a predetermined bending point. During the rollin g process, a forming roller (20) is engaged with rim (12), and is moved progressively parallel with an axis of rotation (A-A). As the forming roller (20) moves, the rim (12) is progressively bent from an orientation normal to an axis of rotation to a position parallel to the axis of rotation. The full y formed rim (12) can then be punched to accommodate a bearing or shaft. This allows a small radius pulley to be formed without use of a mandrel.
